Camp Sense connects to WattIsIt via bluetooth and displays the energy and weather data. The App
folder contains
the React Native app developed using Expo.

A battery watt meter using ADS1115 and a shunt to measure power usage. There are 2 Arduino sketches, Arduino/RemoteXY
and Arduino/Camp Sense
. The latter uses Platform IO plugin for VSCode and works with the Camp Sense app.
AHT21 is optional, was used for humidity but also has a temperature sensor.

Before the Camp Sense app Remote XY was used for development. The sketch is in Arduino/RemoteXY
.
The Remote XY is a free app is used to view data with bluetooh. This also has a setting for the shunt 50, 75, or 100 mV. The setting is persisted in eeprom (flash memory)
